Neb. Rev. Stat. § 44-6133

A mutual insurer may, by not less than a two-thirds vote of the members of its board of directors and with the approval of the director, abandon a plan of reorganization at any time before the issuance of the certificate of authority by the director. Upon such abandonment, all rights and obligations arising out of the plan of reorganization shall terminate and the mutual insurer shall continue to conduct its business as a domestic mutual insurer as though no plan of reorganization had ever been adopted.
